A worker at a coffee shop near Pittsburgh smashed a glass pot over the head of a man as he tried to climb through the drive-thru window to rob the place. Police are looking for the would-be thief and have the encounter recorded on surveillance video. Police say one worker first fought back by throwing towels at the man. When that didn't work, another worker hit him in the head with the pot. Authorities believe the man sped away in a stolen car.
